This invention relates to record controlled accounting and statisticalmachines of the type which may be controlled by means of grouped cardsand arranged to print a group of items read from the cards and thetotals of the items in each group on a series of sheets which maycomprise successive portions of a continuous strip.

In such machines the various items read from the cards are printed andentered in accumulating mechanism or totalizers. When the last card of agroup is read, automatic group control mechanism is called into actionand thereafter causes the machine to go through one or more total andreset cycles during which the totals on some or all the accumulators areprinted and those accumulators are reset. In order that each group ofitems shall be printed on a separate sheet, sheet feeding means isprovided which is brought into operation by the group control mechanismto feed the sheet out of printing posit-ion after the totals have beenprinted and to feed the nest sheet into printing position. On thecompletion of this last operation an automatic re-start mechanism comesinto action to cause the machine to resume operations on the next groupof cards. Thus, each group of items is printed in a separate recordsheet or separate portions (hereinafter referred to as a sheet) of acontinuous strip or web of record material.

It frequently happens that a group of items is too numerous to beaccommodated on a single sheet and an entry control device is thereforeprovided which device is arranged to count the number of lines of itemsprinted on each sheet and to stop the machine as soon as the maximumnumber of lines that can be accommodated has been printed. A machine ofthis kind is described in U. 5. application Serial No. 287,549, filedJune 22, 1928, by F. M. Carroll now Patent No. 1,909,571.

The operation of a machine of this type now known in the art isautomatic only so long as each group of items can be printed on aseparate sheet and the machine stops when a group cannot be printed on asingle sheet. Under the latter conditions. the operator has hitherto hadto manually initiate the following operations:-render the automaticre-st-art mechanism inoperative; initiate a progressive total printingcycle in which totals are printed but the accumulators are not reset; asheet feeding operation of the sheet feeding mechanism; a secondprogressive total printing cycle so that successive identical totals areprinted at the foot of the old sheet and head of 5-5 the new sheet;render the automatic re-start mechanism operative; and, finally, resetthe entry control device which last operation restarts the machine. Itis apparent that numerous manual operations are required so that time iswasted and the possibility of error is large.

It will be understood that the term progres sive total as used above andhereinafter means a total which is printed and retained in theaccumulator without a subsequent clearing operation to reset theaccumulator to zero. The term progressive total printing cycle willrefer to a total printing cycle in which the accumulators are notcleared while the expression total printing and resetting cycle will beused to refer to a total printing operation which includes clearing ofthe accumulators after the total has been printed. In some instances itmay be found desirable, in preparing a statement from one or morerelated groups of records, to reset one or more accumulators afterprinting the totals therein without resetting other accumulators.

It is desired therefore, that the term progressive total be construedbroadly as including a total printed during a mixed cycle of operationsin which only certain accumulators may be reset and the total on saidaccumulators printed without resetting the other accumulators and thatthe term progressive total printing cycle previously defined beconsidered as applicable to such cycle in which only certain of theaccumulators may be reset while others are not reset.

The foregoing paragraph will be more "3; understood if it is noted atthis point that, in th embodiment of the invention to be explainedhereinafter, it may sometimes happen that it is desired to print a totalfrom a balance counter without clearing the latter and at the same timeprint the total from and clear a counter devoted to accumulating entriesfrom a complete group of records. This situation may occur when it isdesired to print the debitand credit items of a single group on separateforms with the balance of'account both at the bottom of the first formprinted and at the top of the succeeding form. Example 1V, describedhereinafter, is an illustration of the foregoing situation. Other mixedcycles may sometimes be desired, as for instance, the one occurringafter the change in major group number in Example V hereinafter described.

According to the present invention there is provided arecord-card-controlled accounting and statistical machine of the abovetype in which the entry control device is arranged to come into actionafter a predetermined number of lines have been printed on a sheet toinitiate automatically (1) a progressive total printing cycle (2) anoperation of the sheet feeding means (3) resetting of the entry controldevice, (4) a second progressive total printing cycle, and (5) restartline printing operations. Thus, when the maximum number of entries havebeen made on a sheet, the machine will proceed automatically to print acarry forward total at the foot of the sheet, feed a new sheet to theprinting line, print the carry forward total at the head of this newsheet, and resume the printing operations with the remaining cards ofthe same group or a related group.

If the last entry of the maximum number of entries is also the lastentry from a group of cards, both the entry control device and theautomatic control mechanism will tend to come into action simultaneouslyor, further, the line spacing operation or operations (usually two)occurring during a total printing and resetting cycle initiated on achange of group may bring the entry control device into action to againinitiate a progressive total printing cycle. In the first case, a totalprinting and resetting cycle would occur simultaneously with aprogressive total printing cycle while in the second case they wouldoccur in succession.

It is desirable that one of these two ways should be followedirrespective of whether the change of group occurs at the last entry orat an earlier entry. Therefore, another feature of this invention is theprovision, in a record-controlled machine, of mechanism for initiating aprogressive total printing cycle and an operation of the sheet feedingmeans, means for bringing the initiating mechanism into action andarranged to be ope ated by the entry control device after the saidpredetermined number of lines have been printed, and means for placingthe initiating mechanism under the control of the automatic groupcontrol mechanism and arranged to be operated by the entry controldevice after a lesser number of lines have been printed, the automaticgroup control mechanism being arranged to bring the initiating mechanisminto action, when so placed under its control, at a time determined bythe automatic group control mechanism.

In many cases there will be no progressive totals to print and, in orderto save time in the operation of the machine, the automatic groupcontrol mechanism is preferably arranged, on

coming into action, to initiate a total printing and resetting cycle, tobring the initiating means into action so that a progressive totalprinting cycle is initiated and occurs simultaneously with the saidtotal printing and resetting cycle.

The lesser number referred to above is less than the predeterminednumber of entries by the number of line spacing operations occurringduring a total printing cycle. Thus, if two line spacing operationsoccur during a total printing cycle, any change of group occurring whenthe antepenultimate, penultimate or ultimate entry in a sheet is madewill result in a total printing and resetting cycle which is also,potentially at least, a progressive total printing cycle.

Conveniently, the sheet feeding mechanism is arranged to resetthe entrycontrol device on the conclusion of a sheet feeding operation, and saiddevice is arranged to initiate a progressive total printing cycle assoon as it has been reset to its starting position.

A preferred embodiment of the invention will now be described, by way ofexample only, with reference to the accompanying drawings, in which:

General arrangement tively, by card feeding mechanism of well-knownconstruction which delivers the cards to a discharge hopper 204.

The upper brushes UB are arranged to read the group numbers of one cardwhile the lower brushes LB are reading the group numbers of thepreceding card and controlling the printing and entry of amounts. Themachine is provided with accumulating mechanism which may include fivecounters or accumulators 200 of the usual construction in which theitems read from the cards can be accumulated, and with printingmechanism 201 by which the items read can be printed on a continuousrecord strip or web. The accumulators 200 may be of the type describedin Patents Nos. 1,307,740 and 1,534,531 while the printing mechanism issubstantially similar to the one described in Patent No. 1,762,145. Thestrip is divided by pre-printed headings into equal sections or lengths(which are hereinafter referred to as sheets) so that the strip can besubsequently cut or severed into separate sheets each having apre-printed heading. The printing mechanism can also be operated underthe control of the counters'to print the totals standing on thecounters. During listing operations the printing mechanism is driven bya listing shaft (not shown) which is driven by a card feed motor FM(Figures 1 and 3). Certain cams, driven by the listing shaft operatecontacts designated by the letter L. During total printing operationsthe printing mechanism is driven by a total shaft (not shown) which isitself driven by a reset motor RM (Figures 1 and 3) through The resetmotor also drives a reset shaft 202 (Figures 3 and 4) through the resetclutch, and

suitable gearing so arranged that the reset shaft is idle during thefirst half of a total printing cycle, but turns through one revolutionduring the second half of such a cycle. Each counter can be reset by agear wheel 205, individual to that counter these wheels being looselymounted on the reset shaft. One part 206 of a counter resetting clutch20620'I is secured to each gear wheel and the other part 207 is splinedon the reset shaft and is spring-pressed away from the part 206.

Each counter resetting clutch is controlled by a separate clutch magnet14 (Figures 1 and 3) which may be energized to effect engagement of theassociated clutch so that the corresponding counter or accumulator 200will be reset to zero when the reset shaft rotates. As this mechanism isnow well known it will not be described in greater detail. Asubstantially similar construction is described in Patent No. 1,933,308granted to James W. Bryce.

The record strip passes round a platen 208 (Figures 3 and 11) which isturned one step after each printing operation by a pawl and ratchetdevice (not shown) in order to line space the strip. The arrangement issuch that, when the printing mechanism is driven by the listing shaft, asingle line spacing movement occurs, while, when the total shaft is inoperation, two line spacing movements occur. This is done in order toprovide a blank space after each total so as to separate that total fromthe first entry of the next group of cards. The mechanism for feedingthe paper strip to accomplish the foregoing result is fully explained inapplication Serial No. 639,153 filed May 15, 1923, byClair D. Lake, nowPatent No. 1,822,594.

Sheet feeding mechanism The platen is secured to a platen shaft 209(Figures 3, 6 and 7) which slides in a sleeve 210 secured to the frameof the machine. A single toothed disc 211 is loosely mounted on thesleeve and carries two driving dogs 213 secured to the ends of a member214 which is splined on the shaft 209 so that the disc and shaft rotateas one. A second disc 215 is mounted on the sleeve 210 and carries adriving pawl 216 which co-operates with the tooth 212 on the disc 211.This disc 215 is coupled by means of a train of gearing 217 to a gearwheel 218 (Figures 3 and 4) secured to a driven clutch member 219 whichis loosely mounted on the resetting shaft 202 and is confined axially bya frame member 220 supporting the shaft 202 and a collar 221 pinned tothe resetting shaft. A driving clutch member 222 is mounted on the shaftand has dogs 223 which extend through slots 224 in the'collar 221 sothat the member 222 rotates with the shaft 202. The driven clutch memher219 is provided with slots 225 to receive the dogs 223 on the drivingmember 222 and a spring 226 located between the collar 221 and thedriving member 222 serves to move the latter away from the driven memberso that normally the dogs 223 do not project into the slots 225 in thedriven member. The clutch just described can be en gaged by energizing asheet feeding magnet 20 when then attracts its armature 22'7, pivoted at228 and engaging at its free end the right end of a slide 229, the leftend 230 of which engages the clutch member 222. When the armature isattracted it moves the slide 229 and the clutch member 222' to the left(Figure 4) thereby effecting engagement of the dogs 223 with the slots225.

A cam 231 (Figure 5) secured to the wheel 218 has a recess 233 in whichrests a tooth on the end of a pivoted lever 234. This lever in turnengages a rod 235 mounted to slide in a bracket 236 and arranged toco-operate with the middle blade of contacts 64 and 66 (Figure 4). Theparts are normally in the position shown in Figure 5. After the magnet20 has been energized and the cam 231 has started to rotate with theresetting shaft, the cam 231 cams the lever 234 and rod 235 to the right(Figure 5), opening the contacts 66 without closing the contacts 64.Towards the end of a revolution of the cam, a cam rise 232 rocks thelever further to the right to close the contacts 64. When the resettingshaft reaches its normal position the tooth in the end of the lever 234drops into the recess 233 in the cam 231 so that the contacts 66 closeand the contacts 64 open.

This mechanism constitutes the sheet feeding mechanism hereinbeforereferred to and its operation is as follows: As items are listed theplaten 208 is fed round step by step and the shaft 209 turnscorrespondingly and consequently the tooth 212 on the ratchet disc 211is moved step by step away from the driving pawl 216. \Vhen the sheetfeeding magnet 20 is energized, the gear wheel 218 is clutched to theresetting shaft 202 so that the pawl disc 215 is coupled to shaft 202which then rotates and drives the pawl disc. During the first part ofthe movement of the pawl disc, the ratchet disc 211 and the platen arestationary but, after a movement depending upon the number of entriesthat have been made, the pawl 216 engages the tooth 212 and the ratchetdisc 211 together with the platen 208 are rotated with the pawl discthrough the remainder of the latters movement. Assuming that the totalmovement of the pawl disc is equal to twenty line spacing movements ofthe platen and that ten entries have been made, then the pawl disc willcommence to drive the platen when it has completed half its movement(equivalent to ten line spacings) and will move the platen through anamount equivalent to ten line spacings. The ratio of the gearing throughwhich the pawl disc 215 is driven can be varied by removing the gearwheels 21'? and substituting wheels of different diameter, therefore themovement of the pawl disc can be made equivalent to the number of linespacings necessary to feed the record strip the length of one sheet.

Entry control device The machine is provided with an entry controldevice 240 (Figures, 3, 8, 9 and 10) This device comprises a pair ofratchet wheels 241 and a circular dial plate 242 having a circularseries of holes 243, both of the wheels 241 and the plate 242 beingsecured to a spindle 246, which is mounted in a back plate 240a of thedevice. Concentric with the dial plate is a pointer 244, carrying at oneend a spring pressed pin 245 which is adapted to pass through the holes243 in the dial plate 242, and extend to the other side thereof. Theholes in the dial plate are suitably numbered to indicate the number oflines which are to be printed and the pointer is adjusted to the numberof lines required and locked by pushing the pin 245 into one of theholes 243. An operating-pawl 250 co-operates with the ratchet and ispivoted at 251 on the armature 252 of an eiectro-magnet 11 so that,whenever the electromagnet is energized, the pawl 250 is operated tofeed the ratchet 241 through one tooth space. A non-return detent 253serves to hold th ratchet in its advanced position. The magnet 11, whichwill be referred to' as the entry counting magnet, is energized, as willbe apparent hereinafter, whenever the platen is advanced one line spaceso that the ratchet wheel 241 together with the screw threaded shaft246, the dial plate 242, and the pointer 244 are moved through one toothspace in a clockwise direction (Figure 8) for each line spacingmovement.

After a certain movement, determined by the position of the pointer 244on the dial plate, the pin 245 on the pointer will engage one end of abell crank 254, the upper portion of which extends just far enough intothe path of the pin 245 to be cammed downwardly (Fig. 8) whenever saidpin strikes the end of the bell crank, thereby rocking the bell crank254 an extent suflicient to close a pair of normally open contacts 60.The bell crank 254' is so positioned with respect to the other parts ofthe mechanism that the contacts 60 close when the entry before thenext-to-the-last entry is made on the record sheet and will be termedthe anticipatory contacts hereinafter since they anticipate the end ofthe record sheet. In the following description the terms ultimate entry,penultimate entry, and ante-penultimate entry will be used in referringto the last entry, the next-tothe-last entry, and the entry prior to thenextto-the-last entry, respectively. Thus, the contacts 60 close on theante-penultimate entry.

The pin 245 may move two additional steps further to engage the upperend of a bell crank 255 when the last or ultimate entry is made. Theupper end of the bell crank 255 extends upwardly an amount suificient tocause said bell crank to rock in a counterclockwise direction when thepin 245 strikes the bell crank thereby closing a pair of contacts 45 toinitiate a sheet feeding operation by energizing magnet 20 in a mannerto be described in detail later herein. If the antepenultimate entry ismade from the last card of a group, a total printing and resetting cyclewill occur and will be accompanied by two line-spacing operations andthe pin 245 will be moved two steps andwill close the contacts 45. Thus,if a total is printed after the antepenultimate entry, it will befollowed by a progressive total printing cycle. This latter cycle willnot, in most cases, result in any totals being printed but it may insome cases result in totals being printed. The function of theanticipatory contacts 60 is to combine these two successive cycles,initiating prematurely the same series of operations as the contacts 45do whenever a total printing and resetting operation follows theantepenultimate entry or the penultimate entry into a sheet. Thus, whenthe anticipatory contacts 60 have been closed and a change in groupoccurs, a total printing cycle occurs in which those counters affectedby the change in group are reset and the rest (if any) are not. Thus, asregards the latter counters, the cycle is a progressive total printingcycle.

The feed pawl 250 is provided with an extension 256 which overlies thenon-return detent 253 and the latter is provided with a pin 257 to theleft (Fig. 8) of an offset lug 258 of a pivoted lever 259 connected at260 to a second lever 261, both levers being pivoted at 262. The secondlever 261 is connected to the armature 263 of a reset magnet 16 and whenthis magnet is energized, it attracts its armature and rocks both thelevers 261 and 259 clockwise.

When the lever 259 is rocked, it withdraws the non-return detent 253 andthe feed pawl 250 from engagement with the ratchet wheel 241.

The entry control device is reset by the energization of a solenoidwhich is mounted upon rods 249, extending behind the back plate 24011 ofthe device. The spindle 246 extends through the back plate 246a and hasa sleeve 246a pinned to its rear end, a thrust bearing 248 beinginterposed between the sleeve and the back plate. A sliding armature 247is mounted in the solenoid and is provided with two key ways 247aengaging two keys 1002) on a plate 100a which is adjustably secured tothe end of the solenoid 100 (see Figure 10). The armature 247 can thusmove axially but is prevented from rotating. The front end 247b of thearmature is formedwith' a quick pitch thread which is engaged by theends of three equally spaced screws 24Gb on the sleeve 246a.

As the ratchet wheel 241 and spindle 246 are stepped round in thedirection of the arrows (Figures 8 and 9) the sleeve 246a rotates andmoves the armature 247 to the right (Figure 9) out of the solenoid 100.When the solenoid is energized it moves its armature to the left (Figure9) and the latter rotates the sleeve 246a and spindle 246counterclockwise (Figure 8) until a stop 264 on the ratchet wheelengages a fixed stop 2640..

Referring to the lower left-hand portion of Figure 1, the reset magnet16 and solenoid 100 are connected to the fixed contact 66 of thecontacts 64, 66, which it will be recalled are controlled by the cani231. Towards the end of a reset cycle cam 231 closes the contacts 64 anda circuit is then established from the left side 13 of the currentsupply line through a relay magnet 65, the contacts 64, a line 62, andcam contacts L P 10 (now closed) to the right side 12 of the currentsupply line.

The magnet 65 also closes its contacts 63 to hold this circuit. When thereset shaft 202 and cam 231 come to rest at the end of a total printingoperation and after the old sheet has been fed out and a new sheet fedin, the contacts 66 close and establish a circuit extending through themagnet 16 and solenoid 100 in parallel and through the contacts 66, thecontacts 63, the line 62, and the cam contacts L P 10. The entry controldevice is thus reset and, on the dial plate 242 reaching its normalposition, a projection 266 on the plate rocks a bell-crank lever 267 toclose a pair of contacts 17. The closure of these contacts initiates aprogressive total printing cycle during which brought-forward totals (ifany) are printed at the head of the new sheet. During the first half ofthis last cycle the cam contacts L P 10 open to de-energize the magnets65 and 16 and the solenoid 100.

The entry control device may also be reset and the machine started bypushing a rod 268 to the left (Figure 8) in its bearings 269. The rodcarries a collar 269a which, when the rod is moved to the left, closes apair of contacts 113. These contacts are in parallel (Figure 1) with thecontacts 63 and, when closed, complete the circuit for the magnet 65.Since the contacts 66 are closed because the reset shaft is in its homeposition, the magnet 16 and solenoid 100 will also be energized-to resetthe entry control device and effect closure of contacts 17. The machinewill then go through a progressive total printing cycle at theconclusion of which the motor FM will be automatically restarted. .Theautomatic restarting of the feed motor FM is efiected by closure of camcontacts P4 near the end of a total printing cycle. The operation of theautomatic restarting circuit is more fully described in Patent No.1,762,145.

It will be seen that in this device the ratchet and dial plate have afixed initial position but that the operative position of the device bywhich it becomes effective to control the machine is determined by theadjustment of the pointer on the dial plate. The functions of variouscontacts controlled by the entry control device will be described indetail with reference to the circuit diagram hereinafter.

Circuit diagram Referring to the circuit diagram the feed motor FM andreset motor RM are controlled in the usual way by a group of circuitsand contacts shown in the upper part of Figure 1. As these circuits arewell known they will not be described, but a detailed description of thestarting circuits may be had by reference to Letters Patent No.1,762,145 granted June 10, 1930. The feed motor FM continues to operateso long as the cards are fed past the brushes and a pair of normallyclosed motor control. contacts MCC remain closed. These contacts arecontrolled by a motor control relay magnet MC which may be energized toopen the contacts MCC and interrupt the circuit of the feed motor.

Counters and printing mechanism The accumulators and printing mechanismare similar to those described in Patent No. 1,822,594 already mentionedto which reference may be had for a more detailed description of theirarrangement. As usual, a printing bank is associated with eachaccumulator or counter.

In order to simplify the drawings, only the circuits for the first orlowest denominational orders of the counters and the circuits forprinting the asterisk adjacent totals have been shown in Figure 2, thesecircuits being designated by the numeral 1 and the symbol respectively,in

.each counter.

The circuits for only the second, third and fourth counters (countingfrom the left, Fig. 3) and associated printing banks are illustrateddiagrammatically in Figure 2 and normally receive their current from thesupply lines 12 and 13 but are supplied from a line 73 through switches81 during the printing of the progessive totals. Each counter isprovided with a bus bar 69 which can be connected to the line 13 througha pair of contacts 71 or to the line 73 through a pair of contacts 72and a switch 81, there being separate contacts 71, 72, associated witheach counter. When the counter resetting clutches 206207 are disengaged,the contacts 72 are closed so as to connect the bus bar 69 to the line73 but the operation of the corresponding counter resetting clutch, as aresult of its magnet 14 being energized, opens the contacts 72 andcloses the contacts 71, connecting the bus bar 69 to the line 13. Theline 73 is connected to the line 13 through normally open contacts 74(Figure 1) controlled by a relay magnet 67-68 having a double wind- Eachprinting bank has an asterisk type bar 280 (Figure 11). This type bar isprovided with an asterisk type 281 in the position corresponding to thedigit 9 on amount printing type bars and is arrested with the asterisktype in the printing position when a total is being printed so that thetotal may be identified by an asterisk. The

printing mechanism is arranged to print the symbol F against allprogressive totals to signify that they are carry forward or broughtforward totals and not the final totals which are indicated by theasterisk. The asterisk type bar is therefore provided with an F type 282in the position corresponding to the digit 1.

Each asterisk type bar is provided with a controlling magnet 86 which,when energized, releases a detent 288 to engage a rack 284 and arrestthe type bar in a position determined by the time in the cycle at whichthe magnet is energized.

The circuit for the asterisk magnet 86 extends from the supply line 12through the lower cam contacts P2, which close as soon as the totalshaft begins to move, to the asterisk line 85 thence in parallel throughthe asterisk magnets 86, contacts 88, the bus bar 69, and the contacts71 to the supply line 13. This circuit is completed prior to the 9 timein the cycle where any magnet 14 is energized to close contacts 71 andresults in the corresponding type bar 280 being arrested with theasterisk type in the printing posi tion. If, however, a progressivetotal printing cycle is initiated, the counter resetting clutches206-207 will not be engaged consequently the contacts 72 will be closedand the contacts 71 opened. The contacts 88 of each counter are alsocontrolled by the corresponding counter resetting clutch magnet 14 whichcloses said contacts when the clutch is engaged and opens them when theclutch is disengaged; It will be clear that during a progressive totalprinting cycle none of the counter resetting clutches will be engagedand all the contacts 88 will be open. The asterisk magnet circuit willthus not be completed until a pair of contacts 89 close. These contacts89 are closed mechanically just prior to the 1" time in the cycle by anysuitable means, such as the means disclosed in Patent No. 1,879,268 foroperating contacts 146 in said patent, so that the asterisk magnet isenergized at this time to arrest its type bar with the F type in theprinting po sition.

control The machine is provided with automatic group control mechanismof a type now well-known in the art, therefore this mechanism will onlybe de scribed briefly. The automatic group control is of a kind similarto that described in Patent No. 1,933,308, mentioned above, except thatthe totals are all printed on a single line instead of on successivelines as in the foregoing patent.

The machine has a major control circuit extending from the supply line13, through lines 194 and 195 (Figure 1), cam contacts L 10, relaymagnets 166 and 25, relay contacts 28, held closed by the magnet 25while cards are being fed, a bus line 35 and a line 34 to the othersuply line 12. A similar intermediate circuit extends through camcontacts L11, a magnet 16611, a magnet 26 and contacts 29, held closedby the magnet 26, while a minor control circuit extends through camcontacts L12, a magnet 166b, a magnet 27 and contacts 30 held closed bythe magnet 27. The cam contacts L10, L11 and L12 open momentarily at theend of each card cycle, but if there is no change in group, as describedin Patent No. 1,933,308, the circuits are maintained through seriallyconnected contacts 191 which are normally open but may be closed by theenergization of an associated magnet 190. The magnets 190 are plugged inseries with the upper and lower brushes which sense together the holesrepresenting group numbers in two successive cards after the fashiondescribed in Patent No. 1,933,308. For a more detailed description ofthe plugging of the control circuits to sense changes in group' numbersreference may be had to said patent.

The machine is shown in Figure 1 as being set up for major control ontwo card columns which contain the group number of the cards andconsequently the two upper sets of contacts 191 have been plugged inparallel with the cam contacts L10, the remaining contacts 191 beingshunted by the closure of switches 193. The upper pair of magnets 190 isplugged each between an upper brush UB reading one of the controlcolumns and the corresponding lower brush LB so that both are energizedif the hole configurations of the control columns in two successivecards agree, but not otherwise. Thus, if there is no change in group,both the upper pair of magnets 190 are energized and both the two uppersets of contacts 191 close and remain closed during the rest of thecycle, shunting (with the plugging arrangement shown) the contacts L10so that the three control circuits are maintained closed. If there is achange in group, however, one or both of the contacts 191 in questionremain open and all three control circuits are broken when the camcontacts L10, L11, and L12 open.

The machine may also be plugged for major and minor group control ormajor, intermediate and minor group control. In case a change occurs ina major group all three control circuits will be broken; a change in anintermediate group results in the intermediate and minor controlcircuits being broken; while a change in a minor group causes aninterruption in the minor circuit only. When one of these circuits isbroken the corresponding magnet 25, 26, or 27 is de-energized, opens itscontacts 28, 29, or 30, respectively, andcloses its contacts 31, 32, or33, respectively.

When any one or more of these three pairs of contacts 31, 32, and 33close, a circuit is set up from the supply line 12 through the line 34,the bus line 35, one or more of the contacts 31, 32, 33 in parallel, aline 36, a relay coil .270, the motor control relay magnet MC and a line37, to the other supply line 13. The relay magnet MC then opens contactsM00 in the motor circuit and brings the motor FM to rest at the end ofthe last card cycle of a group. Towards the end of this cycle camcontacts L1 close and, in a now well-known manner, initiate totalprinting cycle by providing a circuit for the reset motor RM and a resetclutch magnet 78. The reset clutch magnet 78 then engages the resetclutch, so that the total shaft turns through one revolution and totalsare printed. Magnet 78 also closes contacts 79 to provide a holdingcircuit for itself from the line 13, through the motor RM, the magnet78, contacts 79, a line 18 and contacts L2 to the line 12. This circuitis broken at the end ofthe total taking and resetting cycle by the camcontacts P1 which close as soon as the total shaft starts to turn andshort-circuit the magnet 78. The contacts P1 open atthe end of the totalprinting cycle to de-energize the motor RM. During the total printingcycle the contacts LP6, LP7 and L1 8 close and energize the magnets 25,26, 27 so as to set up the automatic control mechanism again. Theenergization of these magnets normally interrupts the circuit for therelay magnet MC .so asto allow of the motor circuit beingre-established, in a known manner, by cam con tacts P4.

The magnet 166 normally holds a pair of contacts 51 open but allows themto close when deenergized on the breaking of the major control circuitWhile the magnets 166a and 16Gb control similar contacts 51a and 51b.The contacts 51, 51a and 51b can be connected by plug connections 53 toany of the counter resetting clutch magnets 14 and in the present casethe contacts 51 are shown as being connected to the magnets 14associated with the second, third and fourth counters. When the majorcontrol circuit fails due to a change in group the magnet 166 becomesde-energized and the contacts 51 close so that a circuit is completedfrom the main line 12 through contacts LP9, switches 54, the magnets 14for the second, third and fourth counters, the plug wires 53, and thecontacts 51 to the supply line 13. The energization of those threemagnets 14 results in engagement of the corresponding counter resettingclutches 206-207 so that these counters are automatically reset afterthe totals on them have been printed. The engagement of the counterresetting clutches also closes the pairs of contacts 71 and 88 (Figure2) to condition the counter circuits for printing the totals andasterisks.

When the magnet 16 is energized, its armature closes a pair of contacts264 (Figures 1 and 8). As soon as the entry control device is restoredto its initial position, the contacts 17 are closed and a circuit is setup from the supply line 13 through .the motor RM, the reset clutchmagnet 78, one

winding 68 of the relay magnet 67-68, the contacts 264 and 17 and thecam contacts L2 to the line 12. The winding 68 then closes the contacts74, which provide a circuit through the winding 67 and the reset magnet78.and the remainder of the reset circuit. The winding 67 holds thecontacts 74 closed until the contacts P1 open and also connects the line73 to the supply line 13 so that totals will be printed from thecounters for which the switches 81 are closed.

Other circuits The sheet feeding magnet 20 (Figures 1 and 4) isenergized, when the magnet 166 becomes deenergized, over a circuitextending from the supply line 12 through cam contacts LP9, the magnet20, a pair of relay contacts 271, a plug connection 57, and the contacts51 to the other supply line. The contacts 271 are closed by the magnet270 which is energized whenever a change of group occurs. It will benoticed that the 010- sure of the contacts 51 resulting from a change ofgroup will complete the circuit through the sheet feed magnet andinitiate a sheet feeding operation.

The counting magnet 11 (Figures 1 and 8) of 3;

the entry control device is energized over a circuit extending from thesupply line 12 through lower card lever contacts LCLC, a switch 15,contacts L8, the magnet 11 and contacts 274 to the other supply line 13.The contacts L8 are closed 1 during listing operation at the 8 point inthe card cycle so thatthe counter receives an impulse and the ratchetwheel is fed through one tooth space during each listing cycle. Duringtotal printing cycles the circuit extends through the cam contacts P5and the magnet 11 receives two impulses, first through upper contacts P5and then shortly afterwards through the lower contacts P5.

When the entry control device reaches its operative position, it, aspreviously explained closes a pair of contacts 45. These contacts are ina circuit extending from the supply line 12, through a switch 70, whichis normally closed but can be opened to render the device inoperative,the contacts 45, a relay magnet 273, and a relay magnet 277, to theother supply line 13.

The relay magnets 273 and 277 are also energized when there is a changein group after the antepenultimate or penultimate entries as follows: Onthe antepenultimate entry the contacts 60 are closed in the mannerpreviously explained. Then, on a change in group, the magnet 270 isenergized and closes the contacts 272, while the magnet MC is alsoenergized to open contacts MCC. Also the reset clutch magnet 78 willbecome energized when the contacts L1 close. The magnet 78 then closes apair of contacts 278 thereby establishing a circuit for the magnets 273and 277 through the contacts 60, 272 and 278.

The relay magnet 273, when energized, closes holding contacts 276 toprovide a holding circuit for the magnets 273 and 277 through thecontacts 276 and contacts 265 which are normally closed but (see Figure8) are opened when the armature 263 is attracted by the reset magnet 16.It is clear, therefore, that the holding circuit will be maintaineduntil the contacts 56 close to reset the entry control device. Therelaymagnet 273 also opens the contacts 274, so as to prevent furtherenergization of the counting magnet 11 and operation of the entrycontrol device, and closes contacts 275.

The closure of the contacts 275, establishes a circuit from the line 13through the contacts 275, a plug wire 56, the sheet feed control magnet20, and the cam contacts LPS to the other supply line 12. The magnet 277closes a pair of contacts 279 to establish a circuit from the line 13through the line 37, the magnet MC, a line 280, and the contacts 279, tothe line 12. The contacts MCC are then opened by the magnet MC and atotal printing cycle follows. The magnet 277 also closes a pair ofcontacts 84 to connect the line 73 to the line 13 and provides a circuitthrough the relay winding 67 via the reset clutch magnet 78, etc. Thecontacts 74 are then closed by the winding 67 and the ensuing cyclebecomes a progressive total printing cycle.

All total printing cycles that involve a sheet feeding operation and thereseting of the entry control device are to be followed by a progressivetotal printing cycle initiated by the entry control device.

' The cam contacts LPG, LP7 and LPS are arranged to close while the camcontacts P4 are closed so that the control circuits may be reestablishedand the magnet MC de-energized before the cam contacts P4 open. Thede-energization of the magnet M0 at this time allows the cam contacts P4to re-establish the circuit for the motor FM and rest-art the card feedin the usual manner.

The contacts 90 serve the prevent this ener gization of the motor FMwhile the entry control device is being reset and thus prepare the wayfor the progressive total printing cycle initiated by that device. Thecontacts 64 close before the contacts LP6, LP7 and LPS and energize themagnet which closes the contacts 90. The latter maintain the circuit forthe magnet MC until after the entry control device has been reset andhas closed its contacts 17 to take charge of the circuit of the motorRM. The contacts 90 are closed during each resetting of the entrycontrol device and thus prevent automatic restart of the motor FMthrough the contacts P4 while the entry control device is being reset.

General operation The operation of the machine will now be explained bymeans of five specific examples. It will be assumed that the machine isto prepare statements of accounts from a batch of cards each of whichcarries a number identifying the customer to which the card relates. Thecards are sorted into groups by customers numberand the machine is setup as shown in Figure 1 and described before herein, so that, in awell-known manner, the cards containing the customers number constitutea major group and control the major control circuit to cause is to failwhen the customers number changes.

The intermediate and minor control will not be required and will be putout of action. This is accomplished by closing switches 193 as in Figurel and positioning the plug wire 192 as shown.

The record strip is divided into separable sheets each of which cancontain ten entries and has space for pro-printed headings. The sheetfeeding means is adjusted so that, when operated, it feeds the recordstrip through a sheet length and the entry control device is adjusted tocome into action after 9 entries (i. e. one less than the capacity of asheet) have been made. Thus when the entry control means comes intoaction there will still be a blank line, on which either a final or acarry forward total may be printed.

The machine is provided with a listing printing bank in addition to theusual five printing banks associated with counters and the machine isadiusted in a well-known manner so that the customers number and dateare both printed by the listing bank. The printing bank associated withcounter No. l is set up in a well-known manner to serve as a secondlisting bank so as to print the invoice number and the code numberidentifying the transaction. The customer number, date, invoice andtransaction numbers are mere ly printed and their totals are notaccumulated in the counters as such totals would be meaningless.

The machine is adjusted in a well-known manner so that all debit amountsare entered into the counter No. 2 and all credit numbers into thecounter No. 3. The debit amounts and the complements of the creditamounts are also entered into the counter No. 4 so that this countercontains the balance of the debit and credit amounts. In the presentinstance the final balance will always be debit so that it isunnecessary to provide a counter for credit balances in which the debitamounts are subtracted from the credit amounts.

The manner in which the balance counter 0p" crates and in which thedebit and credit amounts are separately dealt with is fully explained'inPatent No. 1,896,540 and will not be described herein. The sub-totalswitches 81 for counters Nos. 2 and 3 will be closed but the sub-totalforward record card; 2.A sale of goods or merchandise; 3.A cash paymenton account; 4.Cash discount.

It will be assumed that the first group of cards relates to customer No.23 and contains four cards. Then the machine will print the statementshown in Example I, the dotted lines indicating the extent of one sheet.

When the machine makes the fourth entry of the statement on the sixthline, a change in group takes place, and the three control relays 25,26, and 27 are de-energized completing a circuit from the supply line 12through the lines 34 and 35, the relay contacts 31, 32, 33 in parallel,the line 36, the relay magnets 270 and MC, and the line 37 to the othersupply line 13. The magnet MC then opens contacts M00 in the motorcircuit and brings the motor FM to rest and the magnet 270 closes itscontacts 271 and 272. The relay magnet 166 is also de-energized and itscontacts 51 close. Towards the end of the card cycle the contacts L1close to initiate a total printing and resetting cycle in the well-knownmanner. The magnet 11 also receives one impulse during this cycle byclosure of contacts L8 whereby to move the dial plate 242 one step.

At the beginning of the reset cycle the contacts LP9 set up circuitswhich extend (a) from the supply line 12 through contacts LP9, counterresetting clutch magnets 14 for counters Nos. 2, 3, and 4, the plugwires 53, and the contacts 51, to the other supply line 13 and (b) fromthe supply line 12 through the contacts LP9, the magnet 20, the contacts271, the plug wire 57, and the contacts 51 to the other supply line 13.The energization of the magnets 14 for counters Nos. 2,3, and 4 resultsin these counters being coupled to the reset shaft and in their contacts71 and 88 (Figure 2) being closed and their contacts 72 opened. Themachine will thus proceed to print a total from each of these counters,which totals will be identified by asterisks, and thereafter reset thecounters.

The energization of the sheet feed magnet 20 by closure of contacts 271will engage the sheet feed clutch and bring the sheet feeding means intoaction as described previously. The actual sheet feeding does not,however, occur until the reset shaft begins to turn, which is during thesecond half of the total printing and resetting cycle and after theprinting of totals has been performed.

Thus, the machine will print the total as shown in-the seventh line ofExample I and during the same cycle will feed the sheet forward untilthe first line of the next statement is on the printing line.

, It should be noted that, at the beginning of this total printing andresetting cycle, the contacts 272 have already been closed by magnet2'70 and the reset clutch magnet 78 closes the conmomentarily tacts 278.Later in the cycle the cam contacts P5 close twice to transmit theantepenultimate and penultimate impulses to the counting magnet 11, thefirst of these impulses causing the pointer of the entry control deviceto close the contacts 60. Before the contacts 60 close, however, the camcontacts P1 close and shunt the magnet 78 so that its contacts 278 areopen when the contacts 60 close. Thus, the magnets 273 and 277 are notenergized during the cycle.

Towards the end of this cycle the cam contacts LP 10 close and, sincethe cam rise 232 of cam 231 on the resetting shaft has already closedcontacts 64 as described above, magnet 65 is energized and closes itscontacts 63 to establish a holding circuit for itself and also closescontacts 90 to maintain the magnet MC energized. As the reset shaftfinally comes to rest, the contacts 64 reopen and the contacts 66 closeto provide circuits in parallel with magnet 65 through the contacts'63and 66, the entry control device reset magnet 16, and solenoid 100. Theenergization of these latter magnets results in maintaining contacts 90closed and in the entry control device being reset in the mannerpreviously explained. As soon as the entry control device reaches itsstarting position the pair of contacts 17 are closed.

During the last half of the total printing and reset cycle and aftercontacts 90 have been closed, the contacts LPG, LP7, and LP8 also makeand re-establish the circuit through the group control relay magnets 25,26 and 27, thus closing contacts 28, 29 and 30 and opening the contacts31, 32 and 33. Normally the opening of the contacts 31, 32 and 33 wouldinterrupt the circuit of magnet MC but the closure of the contacts 90 bythe magnet 65 has provided a holding circuit from the supply line 12through the contacts 90, the line 280, the relay magnet MC and the line37 to the supply line 13. The contacts MCC thus remain open and preventrestarting the feed motor FM. The closure of the contacts 17 establishesa circuit from the line 12 through the contacts L2, the contacts 17 and264, the winding 68, the reset magnet 78 and the reset motor RM to theother supply line. The winding 68 then closes its contacts 74 to connectthe line 73 to the line 13 and a second or progressive total printingcycle now ensues with respect to counters Nos. 2 and 3, which have theirswitches 81 closed. Counters Nos. 2, 3, and 4 will not be reset sincethe magnet 166 was energized during the previous total printing cycleand the contacts 51 are therefore open. During the second total printingcycle the asterby closure of contacts 89 with the symbol F" in theprinting position, but no totals will be printed. This cycle, therefore,results in the printing of the symbols F as shown in the first line ofExample II below, and is accompanied by two'line spacing movements sothat the third line of the statement to be used for the next card groupis in the printing position at the end of the cycle. It should be notedthat contacts 264 are held closed at the beginning of the second cycledue to the fact that magnets 100, 65 and 16 are all held energizedthrough contacts 66, 63, and LPlO until, later in such second cycle, camcontacts LP10 open long enough to deenergize all three magnets.Obviously contacts LPlO should not reopen until after contacts 79 haveclosed to establish the shunt circuit around 6011-. tacts 17, 264. Themaintaining of magnet 100 in energized condition during the first partof the second cycle does no harm as magnet 100 is not energized untilafter the contacts P5 have operated during the first total cycle and isdeenergized before contacts P5 operate during the second cycle.

Example II (Preprinted heading) At the commencement of the second totalprinting cycle occurring after the preceding group of cards has beenlisted the contacts LPlO open and interrupt the circuit through therelay 65 which thereupon allows its contacts 90 to open, interruptingthe circuit through the motor control magnet MC and allowing thecontacts MCC to close. At the end of the second total printing cycle thecircuit for the feed motor FM is re-established inthe known manner byclosure of the contacts P4 and the machine proceeds to read, accumulateand list the items from the next card group 24.

When the seventh entry of this group is made on the 9th line of thefirst form or sheet in Example II, the pointer of the entry countingdevice reaches its ultimate position and closes the contacts 45 (Figures1 and 8) which completes the circuit through the magnets 273 and 277.Magnet 273 closes its contacts 276 and thus establishes a holdingcircuit through contacts 276 and the contacts 265 of the entry controldevice and also opens the contacts 274 to break the circuit for thecounting magnet 11 and closes the contacts 275 to energize the statementsheet feeding magnet 20. The magnet 277 closes its contacts 279 and 84,the former contacts energizing the magnet MC, which opens the contactsMCC, and the latter contacts energizing winding 67 which closes thecontacts 74. A progressive total printing cycle follows (since themagnet 166 is still energized and holds the contacts 51 open) in whichthe totals on counters Nos. 2 and 3 are printed together with thesymbols F, but these counters are not reset. As the sheet feeding magnet20 has been energized, the strip is fed forward during the last half ofthis cycle to bring a new sheet into'position. During the last half ofthe cycle the contacts 64 and 66 are operated successively by the cam231 and energize the magnets 65 and 16 and the solenoid 100 so as toreset the entry control device. The magnet 65 closes the contacts 90 tomaintain the magnet MC energized while the reset magnet 16 opens thecontacts 265 to tie-energize the magnets 273 and 277 and closes thecontacts 264 to prepare for a progressive total printing cycle which issub sequently initiated by the closure of the contacts 17 by theresetting of the entry control device.

A progressive total printing cycle takes place as explained inconnection with Example I and the totals on counters Nos. 2 and 3 areprinted with the symbols F but these counters are not reset. After thiscycle automatic restarting of the motor FM takes place through contactsP4 and the remaining items of group 24 are printed. On the last entryfrom the group, the automatic group control mechanism comes into actionand initiates a total printing and resetting cycle accompanied by asheet feeding operation and followed by a progressive total printingcycle exactly as explained with reference to Example I resulting in theprinting of the symbols F on the first line of the following statement.

It will be assumed that the next group 25 contains 7 cards. Then themachine will prepare the statement shown in Example 111.

Early in the seventh card cycle required to prepare this statement thecam contacts L8 close giving the ultimate impulse to the counting magnet11 so that the pointer of the entry control device makes its ultimatestep of movement and closes the contacts 45, energizing the magnets 273and 277, which in turn energize the sheet feed magnet 20 and the magnetMC in preparation for a progressive total printing cycle. Towards theend of the seventh card cycle the cam contacts L10 open and, as there isa change of group, the three control circuits are interrupted so thatthe contacts 31, 32 and 33 all close. The closure of these contacts willnot energize the magnet 270, since it is shunted by the contacts 279 andits contacts 271 and 272 remain open, but the deenergization of themagnet 166 on the failure of the major control circuit results in thecontacts 51 closing. The counter resetting clutch magnets 14 for thecounters Nos. 2, 3 and 4 are thus energized to engage their clutches,opening the contacts 72 and closing the contacts 71 and 88. The printingmagnets are then connected to the supply line 13 by the contacts'71 andare disconnected from the line 73 so that the totals are printedtogether with asterisk symbols. The counters are also reset. At the endof this cycle the magnets 273 and 277 are de-energized, as the entrycontrol device is reset and a progressive total printing device isinitiated exactly as in Example 11. v

The sequence of operations will now be de- 5 are sorted into majorgroups in accordance with the customers number and into minor groups inaccordance with the transaction numbers. As shown in Example IV majorgroup 30 is divided into minor group 2 containing five cards, minorgroup 3 containing two cards and minor group 4 containing one card.

. The machine is plugged for major control on customers number and minorcontrol on transaction number, the magnet 14 for counter No. 4 and thecontacts 271 being plugged to the contacts 51 and the magnets 14 forcounters Nos. 2 and 3 to the contacts 51b. The switches 81 for counters'2, 3 and .4 are all closed. The upper switch 193 in this case will beopen and the lower one closed while a plug wire 192a similar to plugwire 192 is inserted in the plug socket 1922), the latter beingconnected to the series connection between the lower two pairs ofcontacts 191. The manner in which plugging for major and minor controlis effected, is more fully explained in Pat- 'ent No. 1,933,308, hencefurther details are unnecessary herein.

In plugging the machine for control by both major and minor groupnumbers the plug wires are so arranged that the upper two pairs ofcontacts 191 are under control of the holes representing major groupnumber while the third pair of contacts 191 from the top are controlledby the holes representing the transaction number, the lower pair ofcontacts not being used and being rendered inefl'ective by the lowestswitch '193 (Fig. 1) which is closed.

Early in the fifth" card cycle the contacts L8 close and transmit animpulse to the counting magnet 11 which causes the pointer of the entrycontrol device to make its antepenultimate step of" movement and closethe contacts 60. Towards the end of this card cycle the cam contacts L12of the contacts L12. The contacts 32, 33 therefore close energizing themagnets 270 and MC to stop motor FM and thereby bring about aprogressive total printing cycle.

The magnet 16Gb having been de-energized, the contacts 51b close andenergize the counter resetting magnets 14 for counters Nos. 2 and 3, sothat these counters will be reset. The magnet 14 for counter No. 4 willnot be energized, however, since the magnet 166 is still energized andholds the contacts 51 open, there being no change in the major group.The magnet 270 closes its contacts 271 and 272, but the closure ofcontacts 271 has no result as the contacts 51 are still open. The magnetMC being energized to hold contacts MCC open and stop the feed motor FM,a circuit is formed through the reset motor RM and the reset clutchmagnet 78 when the contacts L1 close, as previously explained. Whenenergized, the magnet 78 closes its contacts 278, thereby completing acircuit from the line 13 through the relay magnets 277 and 273, thecontacts 60 (closed when the entry was made on line 7), 272 and 278 andthe switch 70 to the line 12. As before, the magnet 273 closes itscontacts 276 to provide a holding circuit and its contacts 275 toenergize the sheet feed magnet 20 and opens its contacts 274. The magnet277 closes its contacts 84, energizing the winding 67, which closes thecontacts 74and connects the line 73 to the line 13.

The magnet 277 also closes its contacts 279, shunting the magnet 270 andthe contacts 271 and 272 open. The, opening of the latter contacts doesnot deenergize the magnets 277 and 273, since the contacts 276 and 265are closed.

A combined total printing and resetting cycle and progressive totalprinting cycle follow in which the printing circuits for counters Nos. 2and 3 are supplied from the line 13 through the contacts 71 and thesecounters are reset and in which the printing circuits for counter No. 4are supplied from the line 13 through the contacts 74 and 84 inparallel, the line 73, the switch 81 and contacts 72 of this counter,but counter No. 4 is not reset, and the eighth line of Example IV isthus printed. The record-strip is then fed forward by the sheet feedingdevice to bring the first' ple II. As counters Nos. 2 and 3 have beenreset only the balance on counter No. 4 is printed and the sheetisspaced two lines.

The two items of minor group 3 are printed and a change of minor grouptakes place after the entry on the fourth line of this sheet. Themagnets 166D and 27 become de-energlzed so that the, machine performs atotal printing and resetting cycle in which the totals on counters Nos.2, 3 and 4 are printed on the fifth line of this sheet and counters Nos.2 and 3 are reset. Two line spacing movements occurso that the singleitem of the minor group No. 4 is printed on the seventh line. The sheetfeeding magnet will not be energized during the total printing cyclejust mentioned as the contacts 51 and 275 remain open. The contacts 275cannot close since neither the contacts 45 nor contacts 60 have beenclosed. Consequently, closure of contacts 271 and 272 by theenergization of relay 270 has no effect on relay 273 which closescontacts 275.

A change in the major group then occurs and all three control circuitsfail so that the magnets MC and 270 become energized and the contactsandthis counter is reset as well as the counters Nos. 2 and 3.

If a change in major or minor group occurs on the penultimate entry thesequence of operations is similar to that described with reference toExample III, therefore, it need not be described. It will be seen thatthe machine prints a carry for-' ward total on the ultimate entry beingmade if there is no change in major group and will also print a carryforward major total (if required) on a change in minor group after theantepenultimate, penultimate or ultimate entry. 7 The machine may alsobe operated under tabulating conditons, that is to say, only the totalsof a series of major and minor groups are to be printed with each majorgroup on a separate sheet as far as possible. The machine is suitablyplugged and adjusted to tabulate in a wellknown manner. With thisadjustment only a single line spacing operation occurs when a total isprinted and a switch 15 (Figure 1) is opened to disconnect the contactsL8 and lower cam contacts P5 from the line 12. The counting magnet 11thus receives a single impulse through the upper cam contacts P5 duringeach total printing cycle.

The entry control device is adjusted to give one more entry than thecapacity of the sheet, that is to say, if the sheet has 10 lines, as inthe previous examples, the entry control device is adjusted to elevenlines.

Example V, illustrates a case in which major group 11 contains morethanten minor groups.

Etc.

The contacts 60 will be closed by the entry control device on the ninthimpulse being transmitted to the magnet 11, that is, during the printingof the total of minor group No. 8. On the change from minor group 8 tominor group 9 the minor control circuit fails, energizing the magnets2'70 and MC. The magnet 270 closes its contacts 272 while theenergization of the magnet MC results in the resetmotor RM and the resetclutch magnet 78 being energized. The latter then closes its contacts278. A total printing and reset cycle follows in which first the camcontacts P1 close and de-energize the magnet '78 so that the contacts278 open and afterwards the upper cam contacts P5 close and energize themagnet 11. The entry control device, thereupon, advances one step andcloses the contacts 60, but, as the contacts 278 are now open the relaymagnets 273 and 277 are not energized.

The machine therefore resumes tabulating with minor group No. 9 on theconclusion of this cycle.

At the end of minor group No. 9 the minor control circuit is againbroken and the magnets MC and. 2'70 a're energized. The magnet 270closes its contacts 272, and, as the contacts 60 are now closed, therelay magnets 273 and 277 are energized when the contacts 278 close onthe commencement of the total printing cycle. The total of minor groupNo. 9 and a carry forward major totai are then printed on line 10 of thesheet, a new sheet is fed tothe platen, the entry control device isreset and a progressive total printing cycle is initiated all in themanner explained in connection with Example IV. The machine thenresumestabulating operations with the remaining cards of major group No.11. At the end of ,a major group a total printing and resetting cycleoccurs in which both the minor total and the major total are printed onthe same line and all the counters are reset. If the ninth minor groupof Example V had been the last group of the major group, the cycle ofoperation 110 would have been the same except that 'the major totalwould have been identified by an asterisk instead of an F and thecounter containing it would have been reset.

symbols were properly cleared of totals preparatory to accumulating anew series of items and printing the totals thereof.
